BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method of transmitting a broadcastmessage, and more particularly, to a method of transmitting a broadcastmessage in a mobile wireless communication system.

2. Discussion of the Related Art

A broadcast message uses a data burst message to transmit data to all orspecific groups of mobile stations. At the same time, the mobilestations are in a specified mode when receiving the broadcast message.

If the broadcast message is transmitted via a Forward Common ControlChannel (F-CCCH) and a Secondary Broadcast Control Channel (S-BCCH),control information of the broadcast message to be transmitted in sentvia the F-CCCH. For example, the control information includesinformation related to whether the broadcast message has beentransmitted, and Enhanced Broadcast Page information which indicates thelocation of the broadcast message transmitted on the S-BCCH.

According to the conventional method, the aforementioned broadcastmessage is transmitted via the S-BCCH. More specifically, the broadcastmessage is not transmitted via a Primary Broadcast Control Channel(P-BCCH), which is used to transmit an overhead message only, nor viathe F-CCCH. However, the Enhanced Broadcast Page information can betransmitted using a Multi-slot Enhance Broadcast Paging scheme or aPeriodic Enhanced Broadcast Paging scheme.

FIG. 1 is an example showing the Multi-Slot Enhanced Broadcast Pagingscheme. In detail, the Multi-Slot Enhanced Broadcast Paging scheme is ascheme which transmits the Enhanced Broadcast Page information duringF-CCCH slots so that all the mobile stations can receive the broadcastsignal. Here, all the mobile stations are in the slotted mode to receivethe broadcast signal. As illustrated in FIG. 1, if a Maximum PagingCycle period of the F-CCCH is 16 slots, the Enhanced Broadcast Pageinformation can be continuously transmitted in the 16 slots.Furthermore, the Enhanced Broadcast Page information can be received byall the mobile stations receiving different slots on the F-CCCH.

FIG. 2 is an example illustrating a Periodic Enhanced Broadcast Pagingscheme where a BCAST_INDEX is 1. In FIG. 2, information on whether thePeriodic Enhanced Broadcast Paging scheme is being used can bedetermined by the BCAST_INDEX of a Multi-Carrier Radio Resource (MC-RR)Parameters Message. For example, the value of the BCAST_INDEX representby ‘000’ indicates that the Periodic Enhanced Broadcast Paging scheme isnot used. On the other hand, if the value of the BCAST_INDEX is not‘000,’ then the Periodic Enhanced Broadcast Paging scheme having (B+7)broadcast paging cycle period is being used. Here, the value of ‘B’ canbe determined according to Equation 1.B=2^(1+i)×16 1≧i≧7   [Equation 1]

In Equation 1, i represents a value of the BCAST_INDEX transmitted viathe MC-RR parameters message.

In FIG. 2, the value of the BCAST_INDEX is ‘1’ and when applied toEquation 1, the value of B is 64 and the broadcast paging cycle is 71.The Enhanced Broadcast Page information is transmitted via a firstF-CCCH slot of the broadcast paging cycle, and the Enhanced BroadcastPage information includes BCCH_INDEX and TIME_OFFSET. Consequently,transmission locations of the S-BCCH and the broadcast message can beidentified by the Enhanced Broadcast Page information.

A plurality of BCCH is classified into Broadcast Control Channel Number(BCN). In detail, the BCN value of the P-BCCH is 1, and the BCN value ofthe S-BCCH can be any number between 2˜8. The broadcast message istransmitted via the S-BCCH after 40×(1+TIME_OFFSET)ms with respect tothe transmission point of the Enhanced Broadcast Page information. Here,the BCN value of the S-BCCH is BCCH_INDEX+1.

As described above, in order to transmit a broadcast message, EnhancedBroadcast Page information, which provides information on whether thebroadcast message is to be transmitted and the transmission location ofthe broadcast message, has to be first transmitted via the F-CCCH.Thereafter, the actual broadcast message is transmitted via the S-BCCH.However, the problem with this transmission scheme is that the actualbroadcast message cannot be transmitted via the F-CCCH.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of thepresent invention, examples of which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers will be usedthroughout the drawings to refer to the same or like parts.

A mobile station (MS) should know whether or not the S-BCCH used fortransmitting a broadcast message is supported. The MS can determinewhether the S-BCCH is supported or not based on the value of theNUM_BCCH_BCAST included in the MC-RR parameters message. For example, ifthe NUM_BCCH_BCAST value is ‘000,’ the MS can determine that the S-BCCHis not supported. On the contrary, if the NUM_BCCH_BCAST value is not‘000,’ then not only can the MS can determine that the S-BCCH issupported, but the number of the S-BCCH supported can also be determinedsince the S-BCCH supported number equals the value of theNUM_BCCH_BCAST.

The present invention can be applied to cases where the NUM_BCCH_BCASTvalue is ‘000’ and as a result, does not support the S-BCCH fortransmitting a broadcast message. In situations where the S-BCCH isunsupported, two transmission schemes can be used, namely, a Multi-slotBroadcast Message transmission scheme, and a Periodic Enhanced BroadcastPaging transmission scheme.

FIG. 3 is an example illustrating the Multi-slot Broadcast Messagetransmission scheme having a maximum paging cycle of 16 slots. Themaximum paging cycle is a paging channel slot cycle having a duration Mslots, such that M=2^(i)×16, 0≦i≦7, where i=MAX_SLOT_CYCLE_INDEX asreceived in a system parameters message. As illustrated in FIG. 3, theMulti-Slot Broadcast Message transmission scheme is a scheme in whichthe broadcast message is transmitted in a sufficient number of assignedslots on the F-CCCH such that the broadcast message may be received byall mobile stations that are operating in the slotted mode. For example,the base station may transmit the broadcast message in N successivepaging slots, where N is the number of slots in a maximum paging cycle.Furthermore, the Multi-slot Enhanced Broadcast Paging scheme can beapplied to cases where the broadcast message fits in a single slot.Here, the base station may send the broadcast message without regard towhether a broadcast paging message, such as periodic enhanced broadcastpaging, is enabled or disabled.

If a base station (BS) consecutively transmits the broadcast messageusing 16 slots via the F-CCCH, each MS can successfully receive thebroadcast message even if each MS in a cell receives the broadcastmessage via different slots of the F-CCCH.

In a Periodic Enhanced Broadcast Paging transmission method, mobilestations can be configured to receive broadcast messages monitor aspecific broadcast slot, namely, the first slot of a broadcast pagingcycle. Furthermore, if a plurality of broadcast messages to betransmitted fit within the first slot of a broadcast paging cycle, theymay all be transmitted in this first broadcast slot. However, if asingle broadcast message to be transmitted occupies more than one slot,the broadcast message bay be transmitted beginning with the firstbroadcast slot.

FIG. 4 is an example illustrating a Periodic Enhanced Broadcast Pagingtransmission scheme according to a first embodiment of the presentinvention. In FIG. 4, a value of the BCAST_INDEX, transmitted via aMC-RR parameter message, is 1,’ and three (3) broadcast messages aretransmitted via a single slot. If plurality of broadcast messages istransmitted via a single slot, the broadcast message can be transmittedin the first slot of the next broadcast paging cycle. In addition, inthe present embodiment, it is unnecessary to independently transmitEnhanced Broadcast Page or put differently, information pertaining tothe slot used to transmit the broadcast message via the F-CCCH.Furthermore, the S-BCCH is not used.

FIG. 5 is an example illustrating a Periodic Enhanced Broadcast Pagingtransmission scheme according to a second embodiment of the presentinvention. In FIG. 5, a value of the BCAST_INDEX, transmitted via aMC-RR parameters message, is ‘1,’ and the size of a broadcast messageoccupies three (3) slots. As illustrated in FIG. 5, if there is only onebroadcast message to be transmitted and the broadcast message has to betransmitted using three slots, the broadcast message can be transmittedusing three consecutive slots, starting with a first slot of the nextbroadcast paging cycle. In this embodiment, as is the case with thefirst embodiment, it is unnecessary to independently transmit EnhancedBroadcast Page. Furthermore, the S-BCCH is not used.

FIG. 6 is an example illustrating a Periodic Enhanced Broadcast Pagingtransmission scheme according to a third embodiment of the presentinvention. In FIG. 6, a value of the BCAST_INDEX, transmitted via aMC-RR parameter message, is ‘1,’ and there are three broadcast messagesto be transmitted. As such, the first slot (i.e., slot 0) includes threebroadcast paging messages (i.e., enhanced broadcast pages) to betransmitted. Here, each enhanced broadcast page is associated withsubsequent broadcast slots. For each enhanced broadcast page, anassociated broadcast message may be transmitted in the associatedsubsequent broadcast slot. As depicted in the figure, the first enhancedbroadcast page is associated with a first broadcast message whichoccupies slots 7-8. Also, the second and third enhanced broadcast pagesare associated with the second and third broadcast messages which occupyslots 14-17 and slot 21, respectively.

The broadcast slots for the associated broadcast message is determinedaccording to a time offset specified in the enhanced broadcast page. Inaddition, broadcast slots for a repeat of the broadcast message can bespecified via a time offset from the slot of the first broadcastmessage.

In short, in the present embodiment, as described above, there is atleast one broadcast message to be transmitted, and the size of eachbroadcast message may exceed permitted size for each slot. Asillustrated in FIG. 6, in the first slot of the next broadcasting pagingcycle, an enhanced broadcast page, which provides whether the broadcastmessage is transmitted as well as the location of the broadcast messageson the F-CCCH, is transmitted. Here, the S-BCCH is not used.

Furthermore, the broadcast message corresponding to each enhancedbroadcast page should be transmitted after ‘n’ number of slots. That is,a first broadcast message corresponding to a first Enhanced BroadcastPage is transmitted after ‘n’ slots, a second broadcast messagecorresponding to a second Enhanced Broadcast Page is transmitted after‘2n’ slots, a third broadcast message corresponding to a third EnhancedBroadcast Page is transmitted after ‘3n’ slots, and k-th broadcastmessage corresponding to k-th Enhanced Broadcast Page is transmittedafter ‘k×n’ slots.

FIG. 6 illustrates an example where n=7. In FIG. 6, since there arethree broadcast messages to be transmitted and n=7, the first broadcastmessage corresponding to the first Enhanced Broadcast Page istransmitted after 7 slots, the second broadcast message corresponding tothe first Enhanced Broadcast Page is transmitted after 14 slots, thethird broadcast message corresponding to the third Enhanced BroadcastPage is transmitted after 21 slots, and so forth.

The Enhanced Broadcast Page information can be transmitted via a GeneralPage Message (GPM) or an Universal Page Message (UPM). The followingTable 1 is an example of a GPM format according to the presentinvention. TABLE 1 Field Length (bits) GPM Common Fields: CONFIG_MSG_SEQ6 ACC_MSG_SEQ 6 CLASS_0_DONE 1 CLASS_1_DONE 1 TMSI_DONE 1 ORDERED_TMSIS1 BROADCAST_DONE 1 RESERVED 4 ADD_LENGTH 3 ADD_PFIELD 8 × ADD_LENGTH PDUFormat for a mobile station-addressed page: SERVICE_OPTION 0 or 16 PDUFormat for broadcast Page: There is no Layer 3 field associated withthis record.

PDU Format for an enhanced broadcast page when NUM_BCCH_BCAST=‘000’;There are no Layer 3 fields associated with this record.

As shown in Tables 1 and 2, when the value of NUM_BCCH_BCAST is not‘000,’ the S-BCCH is available to transmit the broadcast message, andtherefore, information for receiving the S-BCCH is transmitted. On thecontrary, if the value of NUM_BCCH_BCAST is ‘000,’ there is no S-BCCH bywhich to transmit the broadcast message. As such, the broadcast messageis transmitted via the F-CCCH, and it is unnecessary to transmitinformation pertaining to the broadcast information.

Table 3 is another example of a GPM format according to the presentinvention.

PDU Format for an enhanced broadcast page: BCCH_INDEX 3TIME-OFFSET 10  REPEAT_TIME_OFFSET 0 or 5 ADD_BCAST_RECORD 0 or 8 ×EXT_BCAST_SDU_LENGTH

A field corresponding to ‘PDU Format for an enhanced broadcast page’ inTable 3 can include different information depending on whether theS-BCCH is supported. In other words, different information can beincluded depending on whether the value of NUM_BCCH_BCAST is ‘000’ ornot. For example, if the value of NUM_BCCH_BCAST is not ‘000,’ the BSsets the value of the field corresponding to ‘PDU Format for an enhancedbroadcast page’ to a valid value depending on the transmission format ofthe broadcast message. At the same time, the MS uses the valid valuetransmitted from the BS to receive the broadcast message.

Alternatively, if the value of NUM_BCCH_BCAST is ‘000,’ the BS can setthe value of the field corresponding to ‘PDU Format for an enhancedbroadcast page’ as an unused value or an insignificant default value. Insuch a case, the MS determines that the value of the field is an invalidvalue and therefore does not use the value to receive the broadcastmessage.

For example, if NUM_BCCH_BCAST value is ‘000,’ the BS can set the valueof the BCCH_INDEX as currently unused value. At the same time, the BScan set the value of TIME_OFFSET to be an insignificant value such as‘0000000000.’ In addition, the value of the REPEAT_TIME_OFFSET and thevalue of ADD_BCAST_SDU_LENGTH can be excluded by setting the value ofEXT_BCAST_SDU_LENGTH_(‘)IND to ‘00.’

A field corresponding to ‘PDU Format for an enhanced broadcast page’ inTable 4 can include different information depending on whether theS-BCCH is supported. In other words, different information can beincluded depending on whether the value of NUM_BCCH_BCAST is ‘000’ ornot. For example, if the value of NUM_BCCH_BCAST is not ‘000,’ the BSsets the value of the field corresponding to ‘PDU Format for an enhancedbroadcast page’ to a valid value depending on the transmission format ofthe broadcast message. At the same time, the MS uses the valid valuetransmitted from the BS to receive the broadcast message.

Alternatively, if the value of NUM_BCCH_BCAST is ‘000,’ the BS can setthe value of the field corresponding to ‘PDU Format for an enhancedbroadcast page’ as an unused value or an insignificant default value. Insuch a case, the MS determines that the value of the field is an invalidvalue and therefore does not use the value to receive the broadcastmessage.

For example, if NUM_BCCH_BCAST value is ‘000,’ the BS can set the valueof the BCCH_INDEX as currently unused value. At the same time, the BScan set the value ∘ TIME_OFFSET to be an insignificant value such as‘0000000000.’ In addition, the value of the REPEAT_TIME_OFFSET and thevalue of ADD_BCAST_SDU_LENGTH can be excluded by setting the value ofEXT_BCAST_SDU_LENGTH_IND to ‘00.’

With respect to the enhanced broadcast page scheme, if the samebroadcast message or the same enhanced broadcast page information is tobe re-transmitted, the initially transmitted broadcast message or theenhanced broadcast page information should be re-transmitted after aspecified time period from the initially transmitted time. For example,the re-transmission should take place within (4×(B+7)) slots of theinitial transmission.
